CABLE-HOLDER.

Specification of Letters Patent.

Application filed December 26, 1914. Serial No. 879,144.

tion of the invention, such as will enable others skilled in the art to which it apper tams to make and use thesame.

My invention relates to improvements in line, rope or cable holders of the type particularly designed to hold the choker of hoist mechanism against slipping from'the obj ect to which it is attached when the main line is slackened.

Another object of my invention is to provide a holder that will permit a line or cable to be pulled freely in one direction but lock and prevent the line being pulled in the opposite direction, said holder being particularly designed for use in connection with logging apparatus but capable of being used for various other purposes and being of simple and reliable construction. 7 I

holders of Another object is to improve the character described so as to render them more practical, and reliable in operation without increasing the cost of manufacture thereof.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a side elevation of my improved holder, Fig. 2 is a top plan view,'Fig. 3 is a horizontal sectional view showing a cable or line in position relative to the holder, Fig. 4: is a longitudinal sectional view taken on line d-d of Fig. 2, and Fig. 5 is a fragmentary plan view of the hinged portion of the block or holder.

Referring to the drawings by characters of reference, the numeral 1 designates as an entirety a block consisting of a relatively stationary body portion 2 and a hinged or pivoted section 3 that is hingedly or pivotally secured to the member 1 and arranged to cooperate therewith in holding the cable or line. a

The relatively stationary body 2 is comparatively flat and elongated, and constructed of any desired material. An'opening or eye 4 is formed in one end of the body 2 preferably the smaller end thereof, said body being tapered toward one end. cable receiving groove 5 is formed transversely of the body 2 adjacent to the other or larger end thereof and is approximately semi-circular in cross section. Spaced enlarged portions 6 are formed upon the larger end of the body 2 and receive therebetween a reduced extension or arm 7 carried on the hinged section 3 of the device. A pivot pin 8 is inserted transversely through the portions 6 and extension 7 and hingedly or pivotally secures the section 3 to the body 2 at one end thereof. The under faces of the members 6 at the inner ends thereof are curved so as to conform to the curvature of the groove 5 in the body 2 as clearly shown in Figs. 1 and 4:.

. The sectionor side 3 is of approximately rectangular form and relatively flat and formed at its free end with an apertured extension 9. The apertured extension 9 is designed to extend within a recess 10 which is formed within an enlargement 11 formed on the smaller end of the body 2. A spring pressed locking plunger 12 is slidable transversely through the enlargement 11 and ar ranged to extend through the apertured extension 9 and into an opening 13 formed in one wall of the recess 10. The member 12 is disposed with its head 11 exteriorly of the body 2 so that it may be grasped and withdrawn from the apertured extension 9. The outer face of the hinged section 3 is designed to be disposed flush with the enlargements 6 and 11 at the ends of the body 2 and said section 3 is slightly tapered to "conform to the inclined sides of the body 2. The member 3 is enlarged at the inner end thereof and formed upon the inner face of said enlarged end with an inwardly extending recess 15 covered by a suitable cover plate 16. The sides of the recess converge toward the center of the member 3.

Pivoted centrally within the recess 15 is a friction pawl 17 The inner enlarged end of the member 3 is curved to conform to the curvature of the groove 5 and it will thus be seen that when the device is assembled the cylindrical cable receiving opening is provided transversely therethrough.

The free end of the friction pawl 17 when in alinement with the longitudinal axis of the device or in position at right angles to the groove or opening 5 extends into the opening or groove and is curved as at 18 so as to conform to the shape of the cable to which it is to engage. Upon movement of the pawl 17 to one side of the center or from position as shown in Fig. 5 it is disposed in a position out of engagement with the cable or rope that is slidable through the block.

As a means for preventing the friction pawl 17 from moving into position whereby it will not engage the rope or cable I provide expansive springs 19 and 20 arranged on opposite sides of and within the recess 15 to engage the pawl 17 upon its movement in either direction and to limit the movement of the pawl so that the free end is always in a position to be engaged by the cable.

In use the cable or rope is placed within the groove 5 and the hinged section 3 in the block locked in place by means of the bolt 12. When this arrangement is had the pawl 17 is disposed angularly as shown in Fig. 3 and in such position that the cable is permitted free movement through the block in the direction of the arrow shown in Fig. 3 in the drawings. When the cable is pulled as indicated by the arrow it meets with no resistance from the pawl 17 but when a pull is communicated thereto in the opposite direction the pawl 17 will immediately be moved into gripping engagement with the cable and check its movement. The springs 19 and 20 prevent the pawl 17 from becoming deranged and the positive holding action of the device is thus insured.

With reference to the foregoing deScrip tion it will be readily seen that I have provided a cable or rope holder that will prove of great service in logging devices for preventing the choker line from becoming detached relative to the object to which it is secured when slack is occasioned in the main line or for other line holding purposes.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efiicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.

What is claimed is l. A cable holder including a block having a cable receiving opening extending transversely therethrough, a locking pawl pivotally carried by the block, a recess in said block to receive said pawl, said pawl being arranged to move laterally relative to and extending into the cable receiving opening to engage the cable, and spaced independently operable springs carried on opposite sides of and within the recess to engage said friction pawl and limit the movement thereof in either direction and yieldably urge the said pawl toward the cable receiving opening.

2. A cable holder comprising a relatively stationary body portion, a hinged section hingedly secured to the body portion, a cable receiving opening formed through the hinged section and body portion, said hinged section having a recess therein communieating with the cable receiving opening, a friction pawl pivoted within the recess, and means to limit the movement of the friction pawl in either direction so as to prevent it from being moved out of the cable receiving opening entirely.

3. A cable holder comprising a relatively stationary body portion, a hinged section hingedly secured to the body portion, a cable receiving opening formed through the hinged section and body portion, said hinged section having a recess therein communicating with the cable receiving opening, a friction pawl pivoted within the recess, means to limit the movement of the friction pawl in either direction so as to prevent it being moved out of the cable receiving opening entirely, and means to lock the hinged section to the body portion.

In testimony whereof I aflix my signa ture in presence of two witnesses.
